Compositions, dispensing systems and methods for providing sensorial and aesthetic benefits to acne prone skin

Abstract

A cosmetic composition includes at least one beta hydroxy acid selected from -n-octanoylsalicylic acid, salicylate, sodium salicylate, willow extract, beta hydroxybutanoic acid, tropic acid, and trethocanic acid present in a hydroalcoholic gel dispersion that includes at least one C2-C5 alcohol, (ii) a blend of at least two powders selected from inorganic powders and organic powders, and (iii) at least one polymer. The cosmetic composition may be dispensed using a porous applicator and is applied as an on-the-go skin refresher that is especially good for acne-prone skin. The cosmetic composition can be used throughout the day to control shine and minimize skin imperfections and discourage acne and is suitable for use alone or over or under make up.
